Cialis, containing tadalafil, treats erectile dysfunction (ED) by increasing blood flow to the penis. It also treats benign prostatic hyperplasia (BPH), a condition causing enlarged prostate.
How Cialis Works
Tadalafil relaxes blood vessels, allowing for improved blood flow. For ED, this facilitates an erection in response to sexual stimulation. For BPH, it eases urinary symptoms by relaxing prostate muscles.
Cialis Dosage and Administration
- For ED, the usual starting dose is 10mg taken as needed, at least 30 minutes before sexual activity. For BPH, a daily dose, typically 5mg, is prescribed. Your doctor will determine the appropriate dose based on your individual needs and health conditions.
Important Considerations
Cialis is not a performance enhancer; sexual stimulation is still necessary for an erection. Side effects can include headache, flushing, nasal congestion, muscle aches, and indigestion. Inform your doctor about any side effects you experience. Cialis can interact with other medications, particularly nitrates. Always inform your doctor about all medications you are currently taking. Consult a healthcare professional before taking Cialis if you have heart problems, liver or kidney disease, or a history of stroke or heart attack.
Cialis vs. Other ED Treatments
Cialis differs from other ED medications in its duration of action. While some medications are effective for a few hours, Cialis’s effects can last up to 36 hours, earning it the nickname “the weekend pill.” This longer duration is not suitable for everyone, so your doctor will guide you towards the right choice.
